Infiniti QX50 Transmission Fluid Capacity

Elegantly crafted and technologically advanced, the Infiniti QX50 has emerged as a true contender in the realm of luxury compact crossovers. Introduced in 2014, it quickly gained recognition for its robust performance, plush interior, and exceptional driver-assistive technology.

Since then, Infiniti has continuously redefined the QX50, enhancing its features and performance with every subsequent model, particularly with the introduction of the second generation in 2019. The QX50’s journey over the years demonstrates Infiniti’s commitment to constant innovation and luxury.

While the spotlight often shines on the more visible elements of the QX50, like its bold exterior design or its state-of-the-art infotainment system, one element plays a quiet yet crucial role in ensuring your vehicle’s top-notch performance – the transmission fluid.

The transmission fluid acts as the lifeblood of the transmission system, reducing friction among moving parts, cooling the system, and keeping it clean from debris. Without the correct type and amount of this fluid, the transmission could overheat, components could wear down prematurely, and shifting could become less smooth, leading to a less enjoyable and potentially unsafe driving experience.

Understanding your Infiniti QX50’s transmission fluid capacity, type, and maintenance needs are crucial for preserving the performance and longevity of your vehicle.

Infiniti QX50 Transmission Fluid Capacity And Transmission Fluid Type

The Infiniti QX50’s history is marked by advancements in design, performance, and transmission technologies, all of which contribute to its reputation as a top-tier luxury compact crossover. Let’s explore these generations and their respective transmission types.

Understanding the transmission types of the different QX50 generations is vital as the type of transmission fluid and the change intervals can vary depending on the specific type.

For the first generation of the Infiniti QX50, the manufacturer recommends using Nissan Matic S ATF. For the second generation, it is necessary to use the Nissan CVT Fluid NS-3. These automatic transmission fluids are designed to provide excellent lubrication, cooling, cleaning, and sealing properties for your vehicle’s transmission. They are also developed to offer smooth shifting in all temperature conditions.

While the manufacturer’s recommended fluid is always the best choice, there might be situations where it’s unavailable, and you need to choose a compatible alternative.

2014-2017 Infiniti QX50 Transmission Fluid Capacity

The first-generation QX50, introduced in 2014, was equipped with a 7-speed automatic transmission. This transmission type was chosen for its smooth shifting and efficiency, creating a comfortable and responsive driving experience.

2015 Infiniti QX50

The 2016 facelift retained this transmission type but included enhancements such as an updated exterior and interior design and improved technology.

For the first-generation Infiniti QX50 and its 2016-2017 facelift, equipped with a 7-speed automatic transmission, the transmission fluid capacity is approximately 9.7 quarts (9.2 liters). This is the total amount of fluid the transmission holds, which includes the fluid in the transmission itself and the fluid in the torque converter.

2019-Present Infiniti QX50 Transmission Fluid Capacity

n 2019, Infiniti unveiled the second generation QX50 (J55). In a significant departure from the first generation, this iteration of the QX50 introduced a Continuously Variable Transmission (CVT). The CVT is designed to provide a smoother driving experience by eliminating the noticeable shifts in gear that occur in a traditional automatic transmission. This technology allows for more efficient fuel usage and improved overall performance.

2020 Infiniti QX50

With the introduction of CVT in the second-generation Infiniti QX50, the transmission fluid capacity changed. The transmission system in this generation holds approximately 9.3 quarts (8.8 liters) of transmission fluid. As with the first generation, this capacity includes the fluid in the transmission and the fluid in the torque converter.

These capacities are approximate, and the actual required amount of transmission fluid may vary slightly depending on several factors, including the condition and temperature of the existing fluid. Therefore, it’s always crucial to check the fluid level using the vehicle’s dipstick or appropriate electronic tools after a fluid change.

Optimal Change Intervals

Transmission fluid is not meant to last forever. Over time, the fluid’s effectiveness can decrease due to heat, friction, and contamination, reducing its ability to lubricate, cool, and clean the transmission. This is why it’s important to change your transmission fluid at optimal intervals.

For the Infiniti QX50, both first and second generations, Infiniti recommends changing the transmission fluid approximately every 60,000 miles under normal driving conditions.

However, if your driving conditions are more severe, such as extensive idling, towing, or off-road driving, the change interval should be shortened to every 30,000 miles.

Factors Affecting Change Intervals

Several factors can influence the optimal transmission fluid change intervals for your Infiniti QX50. These include:

  1. Driving Conditions: As mentioned, severe driving conditions, like frequent stop-and-go traffic, extended idling, and heavy-duty usage, can accelerate the degradation of the transmission fluid, necessitating more frequent changes.
  2. Driving Habits: Aggressive driving, such as rapid acceleration and deceleration, can generate more heat in the transmission and degrade the fluid faster.
  3. Climate: Extreme temperatures, both hot and cold, can affect the fluid’s viscosity and its ability to lubricate and cool the transmission.

Regularly checking the color and smell of your transmission fluid can provide a good indication of its condition. Fresh fluid is typically clear and has a slight sweet smell, while fluid that needs changing may be dark and have a burnt odor.

Infiniti QX50 Cost of Transmission Fluid Change

Routine transmission fluid changes are an essential part of vehicle maintenance that can help avoid more costly repairs down the line. However, the cost can vary based on several factors.

The cost of changing the transmission fluid in an Infiniti QX50 can vary depending on where you live and where the service is performed. On average, you can expect to pay between $210 and $290 for a transmission fluid change. This cost typically includes the labor for changing the fluid and the price of the new fluid itself.

Factors Influencing the Cost

Several factors can influence the cost of a transmission fluid change, including:

  1. Labor Rates: The labor cost will depend on the hourly rate of the mechanic or service center performing the fluid change. Dealerships might charge more than independent repair shops or quick lube shops, but they also usually offer a high level of expertise.
  2. Fluid Type: The type of transmission fluid used can affect the cost. Synthetic fluids usually cost more than conventional fluids, but they often provide better performance and longevity.
  3. Location: Prices for services can vary based on the cost of living in different areas. Major cities or regions with a high cost of living might have higher prices for a transmission fluid change compared to smaller towns or regions with a lower cost of living.

While a transmission fluid change comes with a cost, it is a valuable investment in your vehicle’s health. Regular fluid changes can help ensure that your QX50’s transmission works smoothly and efficiently, contributing to a better driving experience and potentially saving you from expensive transmission repairs in the future.
